概括
评估样本细胞性对于初级查中精确的人类乳头瘤病毒 (HPV) 检测至关重要. 低细胞性可能导致假阴性HPV结果,强调需要标准化质量评估指南.
科学领域:
- 妇科 妇科医生 妇科
- 分子诊断学 分子诊断学
- 公共卫生 公共卫生
背景情况:
- 人类乳头瘤病毒 (HPV) 初级查正在取代细胞学,但缺乏标准化的样本质量评估指南.
- 样本细胞性显著影响HPV测试的准确性,与传统的细胞学基础的查不同.
研究的目的:
- 评估样本细胞性对HPV检测准确度在初级查中的影响.
- 通过β-环球蛋白内部控制和定量方法评估的HPV阳性率和样本细胞性之间的关系.
主要方法:
- 使用Cobas 4800 HPV测试对37,592个液体细胞学 (LBC) 样本进行分析.
- 通过测试的β-环球蛋白内部控制 (Ct值) 和定量细胞性评估 (OncoPredict HPV) 评估样本的充分性.
- 根据β-环球蛋白Ct值分层的HPV阳性率 (PR);根据LBC分析HPV阴性样本的子集分析.
主要成果:
- 总体HPV-PR为7.7%,随着β-环球蛋白Ct值较高而显著下降 (Ct≤28为9.7%,Ct>34为1.4%).
- 科巴斯 4800β-环球蛋白 Ct = 34 接近 1.5 × 10^3 核细胞/反应.
- 在19%的样本中发现细胞性不足 (LBC指南),β-环球蛋白Ct≥34;8%的结果≥ASC-US.
结论:
- 样本细胞性评估对于HPV初级查至关重要,以防止潜在的假阴性结果.
- 建立标准化的细胞值是必要的,以提高HPV查的准确性.
- 在LBC样本中的低细胞性可能与细胞缩有关,影响HPV测试可靠性.

Quality Assurance
207
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality Control
315
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
